Applied, thanks!

Note that I made some opinionated follow-up commits on top of this, the main
visible change for you is making the module private and exporting
CommaSeparatedList and Co directly at the top-level proxmox-schema lib.
I also export PropertyString now for consitency, but kept that module public
for the time being to avoid compilation errors.

I also added a few more tests for edge cases, and there I uncovered that,
unlike the module rust doc-comment suggested, validation is currently only done
for deserialization, but not serialization.
That is also the main reason for why I did not yet bump proxmox-schema, as it
would be good to have a short in person discussion if that's really the
behavior we want to have here.
